Study Notes
Dental Unit Waterlines (DUWLs)
- Waterborne diseases are not limited to dentistry.
- Bacteria in DUWLs was first reported over 30 years ago.
- There is not a widespread public health problem regarding contaminated dental water.
- Legionella bacteria cause legionellosis.
- Biofilm is found on any wet or moist solid surface.
- Warm water in dental units contributes to increased bacterial colonization.
- Biofilm cannot be completely eliminated, but it can be reduced.
- Even if sterile water is used in the self-contained reservoir, it will not be sterile when it enters the patient’s mouth because traditional dental units cannot deliver sterile water.
- Microfilters should be changed according to the manufacturer's recommendations.
- Consult the equipment manufacturer when selecting a chemical for the dental unit.
- Sterile water must be used as an irrigant for surgery involving bone.
- Flushing DUWLs will not remove biofilm.
- The high-volume evacuator should be used with the high-speed handpiece, ultrasonic scaler, and air-water syringe to minimize aerosol.
- The use of a rubber dam will decrease, but not totally eliminate exposure to microorganisms.
- Commercial services or in-office test kits can be used to test the quality of dental unit water.
